The timber is restricted to the 

 Northern Forest type, being composed 

 of spruce, balsam, poplar, aspen, 

 birch, banksian pine and balsam fir. 



The total quantity of timber of 

 merchantable size growing in the 

 McKenzie basin is approximately 67 

 billion feet and is distributed as 

 shown by the table on a succeeding 

 page. 



100 Years for Pulpwood 



In addition to saw-log timber there 



are approximately 116 million cords 

 of mixed wood. 



The rate of growth of the trees in 

 the more northerly districts is very 

 slow, so that although it takes only 

 30 years for young spruce to attain 

 pulpwood size under the best con- 

 ditions, it requires nearly 100 years of 

 growth to produce pulpwood timber 

 in the districts adjacent to the upper 

 McKenzie. In sub-arctic regions the 

 rate of growth is almost negligible.
